welcome to the forum. hope you stay for a while and share some pictures of your new watch. i checked the manual for the mtg1500. i see references to a beeper for the alarm and for entering configuration modes and hourly signals. but, i don't see any reference to beeping between modes, nor a 'mute' function (which would silence the mode-change beep). so it seems that this watch may not have that feature! interesting omission (?) on casio's part.I have a new MT-G 1500A - I love it...but I have haven't figured out how to get it to beep when I cycle from one mode to the next. My old MT-G 900 did this...it's very helpful audio feedback. Any comments would be greatly appreciated!
